The printing machine shown is of the type known as an oiiset perfectingpress, but it is to be under- I stood thatthe features and principles ofthis in- 'vention are not to be limited to the particular type 'orprinting machine herein shown; The cylinders 23 and 24in this instanceare the printing or blanket cylinders and receive the impr s ion to beprinted upon the web 22 from form or plate cylinders 2,5 and 28respectively.

The respective cylinders 23-, 24, 25 and 28 are,

arranged to be driveni'rom a shaft 21, which in turnis preferablydrivenby a motor '20 geared to the shaft 21 by bevel gears 29and 1l. Thecylinder! 23 is drivingly connected to the shaft 21by means of a worm 32anda' worm-wheel indicated diagrammatically'in index 24 is driven fromthe cylihder 23 fill-Oughgears 3i and 35, the outer peripheries of theseSears rather than their pitch lines being shown 2 aseassu in dottedlines in Figure 1. The cy1inder25 is Ink fountains 38 and 38 areprovided andcona tain ink for the forms or plates on the cylinders 25and 25 respectively, each fountain 38 and 38 having the usual rotatingfountain roller 4| therein. A swingably mounted ductor roller 421sprovided to take ink from each of the fountain rollers 4| and transferit to a reciprocating ink roller 43, whereover the ink is spread by apair of rollers 44. The ink is then transferred from the roller 43,through rollers 45 and 45, to a pair of reciprocating ink rollers 41 and48, spaced apart about the cylinders 25 and 25.- From each of therollers 41 and 48, the ink is carried to the plates on the cylinders 25and 25 by ink form rollers-48 and 50.

Water fountains 5| and 52 are provided to supply moisture for theprinting plates or forms, each fountain having the usual rotatablefountain roller 53 therein. A swingable ductor roller 54 carries waterfrom the fountain roller 53 to reciprocating moisture rollers 55,wherefrom moisture is carried to and distributed on the plates on thecylinders 25 or 28 by form moistening rollers 55.

As shown in Figure .7, the reciprocating ink rollers and moisture orwater rollers 41, 48 and 55 are arranged to be driven by means ofsuitable gearing from their associated cylinders 25 or 25,

through an idler gear 51 in mesh with the respective gears 35 and 31,and an idler gear pinion 58 rotatable with the gear 51 and in mesh witha gear 58 on one end of a shaft 50 of the respective reciprocating inkor water r'oller. Each of the swingable ductor rollers 42 and 54 arearranged to be swung in the same manner from the respective fountainrollers 4| and 53 to the respective reciprocating ink and water rollers43 and 55, by means of a rotatable cam 5|, one of which cams is shown inFigures 1 and 2, and it will be understood that similar-operatingmechanism is provided for the ductor rollers,

in the lower portion of each printing unit. The cam 5| is arranged to berotated from the shaft of the reciprocating ink roller 41; through anidler gear 52 which is in mesh with the gear 58 on the shaft of theroller 41, and av gear'53 on the shaft of the cam 5| also in mesh withthe gear The connection between the cam5l and the ductor roller 42 (seeFigures 1 and 2), includes a lever 54 secured 'on a shaft 55 extendingbetween and journaled in machine frame members 65 and 51. One of theshaft ends 58 and 58 of the ductor rollers, for instance. the shaft end58 of the roller 42, is journaled in one arm H of the lever 54, and theother shaft end 58 is journaled in one a 12 of a lever 13, which issecured near the othe end of the shaft 55. The other arm 14 of the lever54 is'connected'by a link 15 to an arm 18.which has an arcuate slot 11formed therein, the'arc of the slot 11 being concentric to the pivotalpoint of the link 15 on the arm 14 when the ductor roller 42 is inengagement with the fountain roilef 4|. The link I5 isadjustably-connected to the arm 18 by means of a clamp screw 18'slidable in the slot 11. The arm 15 is secured on one end of a shortrocker shaft 18 which is journaled in the frame member 55. An arm 8Isecured on the shaft 19 50 formed eccentric to the shaft. II.

has a roller 82 on its free end which is adapted to ride on theperiphery of the cam 5|. means of the link 15 and its adjustableconnection with the arm 15 in the arcuate slot 11, the

5 throw of the ductor roller 42 toward the ink roller 43 may be adjusted.to vary the pressure of its engagement therewith without changing thepressure of the engagement of the roller 42 with the fountain roller 4|.

Coiled springs 83 are provided to react between studs 84 secured to theframe members 55 and 51 and the'arm 14 of the lever 54, and another arm85 of the lever 13 to maintain the roller 82 against the cam 5|, andpress the ductor 15 roller 42 toward the fountain roller 4|. A swingablecatch member 85 is pivoted to the frame member 61 and is adapted to beswung'into the path of a lip 81 formed on the end of the arm 85 of thelever 13, to hold the ductor roller 42 20 out of contact with thefountain roller 4|. The

ductor roller 42 is rotatably supported in the arms 1| and 12 in amanner identical with the arrangement for supporting the form rollers 48and 50 and hereinafter described.

The mechanisms (see Figures 1-7 inclusive). for reciprocating the inkand water rollers 43,

41, 48 and 55 are substantially identical and include the gear 58 on oneend of the shaft 50 of the respective roller, and theother end 88 ofthis shaft 60. The shaft end -88, as best shown in Figure '3, extendsthrough the frame member 55, in which it is journaled to rotate on afixed axis, and into an oil-tight casing 88. A worm gear 8| is securedto'the shaft end 88 within thecasing 88 and meshes with a wormgear wheel82 having hubs 83 and 34 journaled in the sides of the casing 88.'Thecasing 88 is supported upon a reduced portion 85 of the end 88 ofthe roller shaft 50 and is reciprocated with the respective ink roller,being guided and prevented from rotating with the shaft by rollers 85and 8 1 pivotally supported on the casing and 'disposed to engage andride one on either side of a bar 88, secured to and extending from theframe member-55. Both ends of the ink roller shaft are journaled inroller bearings 88 secured in the frame members 85 and 51 and areadapted to rotate as well as to slide axially therein. The

50 worm-wheel 82 is provided with an eccentric bore adapted toreceive ashaft ml which is held against axial'movement therein by means of a pinI02 passing through the hub 84 and engaging a groove I03 in the shaftIOIto permit rela- 55 tive rotation between the shaft |0| and theworm-wheel 82. The shaft IN is thus eccentric to the worm-wheel 82 andhas gudgeons I04 and I05 extending from its ends, the gudgeon I04 beinghollow. The gudgeons I04 and I05 are A clamp bolt I05 passes axiallythrough the gudgeon I04 and one end of the shaft IM and isscrewthreadedinto ablock I01 disposed in a recess I08 provided in the shaft m. Theblock I01 is adapted to lock the shaft IM to the wormwheel 82 when thebolt I05 is tightened, by being wedged between an inclined bottomsurface I08 of the recess I08-and the surface III of the bore in theworm-wheel 82.

A screw 2 .is screw threaded into a gudgeon I05 and secures a disc II3in position as shown in Figure 5. The disc 3 is provided with a lugIjja on its inner side which fits into a crossgroove I I4 formed on theend of the gudgeon I05.

The disc |I3 has a hexagon-shaped boss I|3b on assasss its outer sideand it will be understood that by to a member II'Ilfsccured to the framemember 86. Thepivots II1a are in alignment and they are preferablysopositioned that their axis intersects the axis of the shaft end 88. Bymeans of the above described roller reciprocating mechanism, thereciprocating ink and water rollers are given an' axial reciprocatingmovement whenever they are rotated through the gear 58. This movementisdue to the rotation ,of the gudgeons I04 and I05 about the axis ofapplying a suitable wrench to the hexagon boss,

shoulder I23 to engage the pin I25. The long arm I38 of the lever I34has a sleeve |4I (best shown in Figures 12. to 14) secured thereto by anut I42 and has a handle I43 upon its free end. The sleeve I is slidablymounted on a rod I44 and disposed in an'elongated opening I46 formed ina frame I45. The rod I44 passes lengthwise through and is secured tothe'frame I by nuts I41 and I48. The sleeve I is disposed betweencollars I49 and I6I which normally abut against shoulders I52 and I53respectively providedon the frame I45 and which extend inwardly from thesides of 'the opening I46. Springs I54 and I56 coiled about the rod I44react between the collars I49 and I5I and the respectively adjacent endsof the opening I46.

Movement of the rod I44 to the left will swing the lever I34 and relievethe pressure of the spring I38 against the-lug of the arm I33. The armII8 will then be swung downward by gravity and the catch shoulder I24will engage thepin I26 and trip the cylinders-oil? impression" as theworm-wheel 92, whereby the lever H5 is rocked upon its pivotalconnection with the link I.I| and slides the casing 89 along thebar 38and the shaft-.60 of the reciprocating ink and water rollers axially inits bearings in the frame members 66 and 61. By adjusting theeccentricity ofthe gudgeons I64 and I05 relatively to the worm-wheel 32.the length of the stroke of the respective roller may be varied. Dueto-the ,novel arrangement of cranks and levers, the

pivotal connection at which the thrust- 0f the lever H5 is applied tothe link Ill, moves in an elliptical path and the force is exerted withmuch of which is pivotally mounted'on a crank pin II6 extending from andeccentric'to a shaft end I2I hereinafter described.

As shown in Flgurel, the rod I44 extends'along the side of all of theunits 2|. On one of the units therod I44 passes, through a guide M411and collars H417 and H40 are secured to the rod on either side 'of theguide, A spring 411 is placed upon the rod I44 between the guide I440and the collar I440 and acts to force the rod I44 to the right asshownin the drawings, to the extent permitted by the collar I44b.

A switch I56 and conductors I51 provide means to energize a solenoid" I58 or like deviceyto actuate a bell crank I59 and thereby move the rodI44 towards the leftas shown in the drawings, and simultaneously rockthe shafts I3I of all of the units 2I in the proper direction to tripthe cylinders and form rollers ofi impression." If, howso ever, any ofthe levers I39 are locked in eitherthe the rod I 44 by the solenoid.

of the lower printing or blanket cylinder 24. The

other end I22 0f the arm H8 is provided with catch shoulders I23 andI24, one on each side edge thereof. The catch shoulders I23 and I24 areadapted to engage pins I25 and .I26 respectively between which the armIIBcan be swung.

The pins I25 and I26 extend between spaced apart bars I21 and I28, thebar I21 having a squared end I29 adapted to receive a wrench, and thebar I28 being secured on the end of a y, and I26 by the catch shouldersI23 and I24 is controlled includes links I32 connected to the. end I22of the arm II8and to the free end of an arm I33 pivotally supported onthe frame member 66. Th arm I33 is connected to a lever I34 by a rod I35which is pivotally connected to a short arm. I36 of the lever I34 andextends to and through a lug I31 on the arm. I33. A spring I38 is coiledabout the rod I35 and reacts between it and the lug I31 to constantlyurge the arm I33 in a direction to maintain the arm H8 in position forthe shaft I 3I which extends between and is journaled impression on orimpression off position, they obviously will not be affected by themovement of The means whereby the various rollers and cylinders aresimultaneously tripped. in the directions indicated by the arrows I inFigure 1, when the shaft I3I is rocked-in a counter-clockwise directionincludes arms I 6|, (Figure l) secured on the shaft I3I, (Figure 2) andlinks I62 (Figure 1 pivotally connected to the arms I 6| andbeingsecured to and extending to lugs I63 provided on -rings I64 which aresecured to the hubs I65 06 bushings I66.

The bushings I66 are mounted in the frame members 66 andtl'and supportthe bearings I61 of the upper blanket cylinder 23. The bushings I66 arearranged eccentric to the-bearings I61 so that-rotation of the bushingsI 66 will raise the axis of the cylinder 23 and separate its peripheralsurface from thecooperating peripheral surface of the lower blanketcylinder 24. The form and operation of the rings "I64 and the eccentric.bearing supporting bushings I66 shown in operative position in respectto the cylinder 23, is similar to that-efi rings I68, (see Figure '1),which are secured to'the hubs I69 of eccentric bearing supportingbushings "I and support the bearings I13 of the form or plate cylinders25 and 26. The rings I68 are connected by horizontal links I14 (seeFigures 2 and '1). to vertical links I15 at a point I16 spaced from theupper end of the links I15. j

The lower ends of the links I15 are connected *ny bars I11 to arms I18secured on a shaft I19 which extends between and is journaled in the lwhich are secured one on each end of a tubular shaft I84 by screws I85.The tubular shaft I84 is rotatably mounted on and supported by a shaftI88 extending between and joumaled in the frame members 66 and 81. Acoiled spring I81 is provided to react between the arm I82 and astationary stud I88 extending from the frame member 66 to resist therotation of the tubular shaft I84 to rock the bushings Ill, and toseparate the formcylinders 25 and 26 from the blanket cylinders 23 and24 respectively. The spring I81' also similarly acts to resist rotationof the tubular shaft in the opposite direction after it has been movedtotrip the cylinders as described. Thev arm I 83 has an extension I89which is provided with a tool receiving socket I9I by which it, andthrough the hollow shaft I84, the arm I82 may be rotated to turn bothbushings I1I simultaneously.

A spring and ball locked pin I 92 is provided in the extension I89 andarranged to be inserted in an opening I93 provided in an arm I94 to lockthe arm I83 and the arm I94 together.

The arm I94 is rotatably mounted on the end of the hollow shaft I84adjacent .to the arm I83 and has an extension I95 to whichlinks I98 arepivotally secured. The links I96 extend from the extension I95 to an armI91 secured on the shaft I3I adjacent the frame member 61. Rockingmovement of the common rock shaft I3I will, through the links I98 andarm I94 (when the pin I92 is in position to lock the arms I83 and I94together), rock the hollow shaft I84 to cause the cylinder 25 to beseparated from the cylinder 23.v

This rocking movement of the shaft I3I' will also cause the cylinder 23to be separated from the cylinder 24 by turning the bushings I66 througha the arms I6I, the links I62, and the rings I64 in a similar manner.When the pin I92 is withdrawn from the arm I94, only the form cylinder25 will be moved to separate it'from the blanket cylinder 23, when thearm I83 is turned by a tool inserted in the socket I9I.

The handle I8I is used to adjust the impression ressure, or the degreeof engagement of the form on the cylinder 25 with the blanket on thecylinder 23, and a scale I98 and a handle locking means I99, (shown inFigure 2), is provided to indicate such adjustment and to lock thehandle I8I in its adjusted position. When the handle I8I is locked inposition, the shaft-J19 is held stationary and the arms I18 through thelinks I11 hold the lower ends of the links I15 to insure movement of thebushings "I as above described by rocking movement of the hollow shaftI84. 1

The means whereby the form inking rollers 49 and 58 are tripped orseparated from the form cylinders 25 and 26 respectively, includessleeves 28! (see Figures '7 to 9), rotatably mounted upon the hubs I69of the bearing supporting bushings HI, and which are connected by links282, each secured at one of their ends :tolugs 288 provided on thesleeves 28I, and at their other ends to arms 284 and 285 (shown also inFigure 2), which are secured one at each end of the shaft I88 adjacentthe frame members 68 and-81 respectively. A coiled spring 286 isvprovided and arranged to react betweenthe am 284 and the stationary studI88 to resist rotation of the shaft 8 to rock the bushings 28I.

The arm :05 has ascasss 284 may be rocked to simultaneously rock thesleeves 28I. A spring and 'ball locked pin 289 is provided in the armI94 and is arranged to be inserted in an opening 2 provided in theextension 281 to lock the arms 285 and I94 together whereby the sleeves28I will be rocked whenever the shaft I3I is rocked.

The sleeves 28I are each provided with a cylindrical surface 2I2 (shownin Figures -'1 to 9) eccentric to its axis and to the hub I69. A ring 2I3 is rotatably mounted upon each eccentric 2 I 2 and is retainedagainst rotation by links 2I4 pivotally connected at one end to theadjacent frame member 88 and 81 respectively, and at their other ends to9. lug 2I5 provided on the respective ring 2I2. The rings 2I3 are heldagainst the side frames by screws 2I8, screw-threaded into the adjacentframe member 66 or 61, elongated openings 2" being provided in the rings2I3 to permit their movement in the general, direction of the arrow I88,when the sleeve 28l is turned.

Arms 2I8 and-2I9 (see'Figures 8 and 9) pivoted at their adjacent ends-tothe rings 2I2 (intermediate the ends of the form inking rollintowhich-an adjusting. screw 223 is screwthreaded. The screws 223 arerotatably mounted in lugs 224 (see Figure 10), which are pivotallymounted in the ring 2I3. The screw heads 225 are under constant urgeaway from the lugs 224 by coiled springs 228 arranged to react betweenone side of the lugs 224 and the respective screw heads 225. A stop nut221 screw-threaded on each-of the screws 223 is pinned thereto andengages the other side of the lug 224. The springs 228 resilientlymaintain the remote ends 22I of the arms 2I8 and 2I9 in their adjustedposition. V

The arms 2I9 and 2I 8 are connected by links 228 to split ink rollersockets 229 and 23I respectively, and these sockets 229 and 23I arecarried on arms 229a and23 Ia respectively, each of these arms beingrotatably mounted upon the inner end of a supporting sleeve 238 disposedone at each end of they roller 48 and which also act to secure theroller bearing 99 in position. The

sleeves 232 which are eccentric to the axis of the rollers 49 and 58 andhave a central portion reduced in 'diameter so as to form what may betermed a dumb-bell shaped bearing. The sleeves 232 are clamped in therespective bracket 229 and 23I by a clamp screw 233 which acts on'aswings able cap 234 in the usual manner. A roller bearing 235 (seeFigure 7), is disposed in each of the ends 236 and 231 of the sleeves232. Rotation of the sleeves 232 will adjust the respective roller 49 or58 in respect to the reciprocating roller 48 and the amount of thisadjustment is indicated by comparison of a dial and pointer 248.

A vertically extending rod 238 (see Figures 1 are and 2), is connectedat its lower end to the aged from the form.

extension 291 of the arm 235 (see also Figure 16), and at its upperendto one arm 239 of a bell crank 24I pivotally secured to the: framemember, 51 by a screw 242. The other arm 243 or the bell crank 2 isconnected by a horizontal rod 254. The pin 252 may be drawn into the armI39 by pulling upon the'handle I43 and then 1 slightly rotating it tomove the hol 255 pro- 244 to the catch member 35. The rod 244 passesthrough alug 245 provided on the catch member 55. Springs 245 and 241,one on each sideof the lug 245, react between this lug and collars 249and 249 respectively, which are secured to the rod 244. The catch member85 is pivoted to the frame member 51 b a screw 25I and is adapted Themechanism employed to trip the printing cylinders and inking rollers,and the ductor roller operating mechanism of the upper portion of eachof the printing units 2I are shown in Figure -2. Although not shown inthe drawings, it will be understood that tripping mechanism to'be swunginto the path of thelip 81 on the similar to that shown in Figure 2, isemployed for moving the form cylinders 25 away from their ping the formrollers away from the form cylinders 26; also that additional mechanismsimilar to that depicted in Figure 2, is provided for operating theductor rollers and other members that are duplicated in the lowerportion .of the printing The mechanism for tripping the cylinders and,rollers in the lower portion of each unit is operated by a second arm"I91 notshown, but also secured on the shaft I3I, and connected to thetripping mechanism in substantially the same manner as that shown forthe upper portion of the unit. a

During the time that the press is being made ready for a run, andespecially when several men are each working on difierent units of thepress, it is desirable that mechanism be provided whereby the operatorof any unit can so i set the tripping mechanism that the unit will betripped on impression and b locked ther so the impression cannot betripped "off" by an operator on any of the other units, and also, it isdesirable that mechanism be provided whereby the operator can set thetripping mechanism of th unit on which he is working, to trip theimpression 011" and it-will 'belocked there and the-unit will be heldoff impression-until it is unlocked' Manually operated means is providedto separately lock each of the levels I34- (see Figures '2, 12 and 13)in a osition to trip the cylinders and rollers of any unit 2I onimpression, and to lock them in such tripped position, and these meansalso provide for tripping ofl impression, the cylinders and rollers ofany-unit and locking them in such tripped position. These means includea spring pressed vided therein, out of alignment with a pin 255 securedin the arm I39 and protruding therer from. This operation will hold thepin 252 in inoperative position and the lever I34 will be free and canbe swungJiy' the solenoid I53,

through the rod m. It will be, understood that the lever I39 maybeswu'ng'to bring the pin 252 into alignment with the hole 253 and bythen turning the handle I43 to bring the hole Assuming that the printingmachine is in operation and for some reason it is desired to trip orseparate the movable blanket c linder 23 from the other blanket cylinder24, ders 25 and 25 from their cooperating blanket cylinders, and theinking rollers from their respective form cylinders on all of the units2I simultaneously, an operator closes the switch I56 to energize thesolenoid I58. Energization of the solenoid I58 will, through the bellcrank I59, push the rod I44 to the left in Figure 1 to compress thesprings I 55, whereupon pressure will be exerted to turn the lever I34from its normal neutral position to wing the reciprocating arm II8ofeach unit I in the proper direction to cause the catch shoulder I24 toengage the pin I25 and rock the shaft I3I counter clockwise in Figures 1and 2. This rocking movement of the shaft I3I will simultaneously rockthe eccentric bushings I55 to trip all of the blanket cylinders 23, andthrough the link I95 rock the arm I94. As the pins I92 and 209 are bothinserted in their respective openings I93 and 2 in the arm extensionsI95 and 291 respectively when the machine is in operation, rockingmovement of the arm I94 will simultaneously rock the eccentric-bushingsHI and l the sleeves 2M, tripping all of the form cylinders 25 and 25 toseparate them from the respective blanket cylinders 23 and24 and all ofthe ink iorm rollers to separate them .from the form cylinders 25 and25. At the same time that the,

cylinder 23 of one of the units- 2|, the pins I92 and 299 are withdrawnand the shaft I3I may be rocked by a wrench applied to the wrench pin252 (Figure 13) which is slidably mounted in .ed to receive the pin 252and lock the lever I34 in the above-mentioned positions respectively. InFigures 2, 12 and 13, the lever I34 is shown locked in the impressionon" position, with the pin 252 of the arm I33 extending into the hole 7525. and this is accomplishedby withdrawing the lug I29. By withdrawingonly the pin 209 and leaving the pin I92 in looking position, theformcylinders 25 and 25 may be tripped simultaneous- '1 with the blanketcylinder 23 of the selected e form cylinlysdiusted byr r ment with pin:09 and rocking the shaft I85 by a mi inserted in the socket 208. a

From the foregoing, it. will be understood that the printing impressionmay be manually tripped a wrench applied on its squared .end I29. Any

of the form cylinders may be disengaged from its coacting blanketcylinder by withdrawing the pin I 92 from its locking position andturning the socket I91, and the :torm rollers in any printing unit maybeseparated from the form. by withdrawing the pin 209 from its lockedosition and rotating the shaft I86 by a toolv inserted in the socket208.. a

In "machines of this kind as heretofore constructed, the inking rollershave been carried on vertically movable plates or light frame members,by means of which they are lifted from the form, usually by cammechanism, and when the rollers are lowered into engagement with theform they are held in contact with it by gravity,

thus allowing the rollers a certain amount of freedom which permitsthemto bounce as they are engaged and disengaged from the plate or :form asit passes under them. with the eccentrically controlled rolleroperatingmechanism as herein disclosed, th rollers are positively heldin both the non-e and in the engaging,

assasss parting from the spirit or essential attributes thereof, and itis therefore desired that the present embodiments be considered in allrespects as illustrative and not restrictive, and it will 'be furtherunderstood that each and every novel feature and combination present inor possessed v by the mechanism, herein shown and disclosed, the sleeveI84 by means of a bar inserted in I forms a part of the inventionapplication.
